Defraggler and 1.5tb seagate back up

I have been trying to defrag a 1.5tb drive that only has 70 gb of data on it. Originally it said 2 days . Left it on doing its defrag. Came home at midnight and it said 3 hours left. 8 hours later it said 1.5 hours left. Gave up with defraggler and after running windows defrag for 8 minutes, I am at 41 percent already.

Whats the deal? I have the latest version of defraggler...

internal or external drive?

OS and DF versions?

have you turned off VSS, restore points and hibernation file settings in DF?

Seagate back up plus 1.5 tb external.

Defraggler 2.18.945

VSS set to stop

Dont see any setting in df for restore points or hibernation.

Hibernation was turned off a while ago on my system

My drive is not set to back up restore points.

Dave see member kroozer's post in this thread for the settings
